On the first day of full competition in the London 2012 Summer Olympics, Team USA won its first medal of the games, as the men's archery team took silver in a tense final against Italy. The Americans reached the final after stunning the highly regarded South Korean team in a comeback win earlier in the day.

Italy won on its last arrow, when a score of eight would have meant a loss and a ten a gold. The arrow hit the line between the 9 and 10 — and in archery, that meant 10 points, and the gold medal.

Led by world No. 1 Brady Ellison, 23, the three-man American team includes Jake Kaminski, 23, and Jacob Wukie, 26. U.S. archery last won a team gold medal in 1996.
